## What is Clueless in English?

Not sure where to start with English grammar — or with idioms?
Clueless in English brings section-by-section grammar quizzes and native-speaker idiom study together in a single app, so you actually finish what you start.
Instead of plain memorization, you solve, listen, and try again — the way knowledge sticks.

[How it Works]





Pick a grammar section or an idiom topic
Choose today's scope from dozens of grammar categories and idiom topics, or jump straight in with the recommended card.



Quizzes for grammar, cards and audio for idioms
Answer multiple-choice and fill-in grammar questions with instant explanations, and flip idiom flashcards while checking pronunciation with native-speaker audio.



Track your flow with unified stats
Grammar and idiom records build up in one calendar and list, and per-area filters show your weak spots and your streak at a glance.

[Features]
• Grammar and idioms, together
Move between grammar quizzes and idiom flashcards in one app, and focus on just the area you want.

• Native-speaker audio & background playback
Save idiom audio to your device to listen offline, and keep playing even when the screen is off.

• Fine-grained idiom study settings
Toggle the idiom, the meaning, the English example, and the Korean example independently, and adjust auto-advance, repeat counts, playback speed, and intervals.

• Five quiz types
Multiple choice and verb-tense input for grammar; multiple choice (EN->KO / KO->EN) and typing for idioms.

• Unified study stats & calendar view
Visualize your daily activity on a calendar and track results separately with grammar and idiom filters.

[Free Access & Subscription]
Without a subscription you can complete one learning session every day, free of charge.
Subscribe to study every grammar section, idiom category, and audio track without limits.
Subscriptions are managed through your App Store account and can be cancelled at any time.
